Answer:
f(3) = -13
Step-by-step explanation:
f(x)= - x²-4 (not (-x)²)

Answer:
n=23/10
Step-by-step explanation:
10(n+4)=63
n+4=63/10
n=63/10-4
n=23/10
decimal form: 2.3
Answer:
2
Step-by-step explanation:
Given that:
Flawed bulbs = 4
Not flawed = 26
Total examined = (flawed + not flawed)
Total examined = (4 + 26) = 30
P(flawed) = flawed / total
P(flawed) = 4 / 30 = 0.1333333
If 15 is examined :
Expected number of flawed bulbs :
(4/30) * 15 = 2
